Abstract

To improve efficiency and space factor, compressed gas at ambient temperature is supplied to the inside of a housing which contains electrical apparatus to be operated at cryogenic temperature, the gas being expanded and supercooled inside the housing, with possible additional cooling stages located therein; heat exchangers, in the form of heat exchange shields are located within the housing intermediate the housing walls and the electrical devices to be supercooled. Typical electric devices are superconductive coils, cables and the like, the cooling fluid being conducted, if desired, through hollow portions of the devices.
